A hydraulic door locking mechanism for a motor vehicle comprises a manually operable diaphragm piston 7 and a speed-responsive diaphragm piston 17 each adapted to pressurise fluid in a common hydraulic line H supplying slave cylinders 4 for actuating a number of locking bolts 9 simultaneously, the piston 15 being acted on by a rod 3 which is connected to mechanism (not shown) driven from the gear box of the vehicle whereby movement of piston 15 to the position 16 occurs when the speed of the vehicle exceeds a predetermined value. The manually operable piston 7 is secured to a rod 13 movable by a push button 10, a spring-loaded ball (11, Fig. 2, not shown) being engageable with a recess in the rod 13 in the depressed position of the push button to hold the bolts 9 in the locked position with a force sufficient to overcome the effect of release springs 18. When the vehicle is being driven, however, movement of the piston 15 to the position 16, upon exceeding the predetermined speed, overcomes the effect of the spring-loaded ball to return the push button 10 and piston 7, so that when the vehicle subsequently stops the bolts return to released position. Thus, in the event of a crash the occupants of the vehicle are not locked in. The vehicle can also be locked externally by key cylinders 5D, 5G on opposite sides of the vehicle which are coupled to the piston 7 by lost-motion couplings 25, 27 and 26, 28, respectively, a pinion 20 and a rack formed on the rod 13.

Int. 01. Eb65/38, 65/42 U.S. Cl. 70264 2 Claims ABSTRACT OF THEDISCLOSURE The present invention relates to a hydraulic device forsimultaneously locking several panels or doors of vehicles, providing asafety device, at the same time against opening of the said panels ordoors when the vehicle is running and against their undesired locking inthe event of accident.

The device forming the object of the invention comprises means forcontrolling the locking of the panels or doors when the vehicle isstopped, especially key controls for the exterior on leaving thevehicle, and push-button controls for the interior when it is desired toensure its safety when stopped, and means for controlling automaticallythe locking of these panels or doors when the vehicle is travellingabove a certain speed and the suppression of this locking action belowthe said speed, which furthermore provides a safety device for children,and safety against any risk of being locked inside the vehicle in caseof accident.

Other characteristic features of the device according to the inventionwill be brought out in the description which follows below, by way ofexample and without any limitation, reference being made to theaccompanying drawings, in which:

FIG. 1 shows diagrammatically the general arrangement of the device inthe unlocked position;

FIG. 2 is a view in cross-section taken along the line II--II of FIG. 1;

FIG. 3 is a view of a detail;

FIG. 4 represents the' general arrangement of the device in the lockedposition;

FIG. 5 is a view in cross-section taken along the line V-V of FIG. 4.

Referring now to FIG. 1, it can be seen that this device comprisesessentially a manual interior control member -1, an automatic controlmember 2 controlled by a regulator 3 taking its drive from the gear box,receivers 4 with bolts 9, and two external control key members, one onthe right-hand side 5D and the other on the left 5G. A hydraulic circuitH couples together the control members 1 and 2 and the receivers 4.

The control member 1 comprises a push-button 10, the toothed-rack shaft13 of which controls the piston 7 acting on the deformable diaphragm 6inserted in the cylinder of the member 1. The toothed rod 13 is providedwith a cavity 12 and a ball 11 is housed in a guide 11 rigidly fixed tothe cylinder of the member 1, the ball Patented Dec. 23, 1969 "ice beingsubjected to the action of a spring 14 and coming into engagement withthe cavity 12 during the movement of the rod 13.

The toothed rod 13 is associated with a pinion 20 rotatably mounted onthe shaft 21 and having no effect on the external control devices SD-SG.Each of the devices 5D and 5G comprises a barrel of known type withalternative movement to the right or to the left, having the purpose ofactuating the pinion 20 and the toothed shaft 13 'by means of anextension 22 coupled on the one hand to the nose of the barrel and onthe other hand to a part 23 or 24, independent of each other, butoperating through a dog 25 or 26 the pinion 20 which is in turn providedwith two projections 27 or 28.

The automatic control device comprises the regulator 3, taking its drivefrom the gear-box of the vehicle, acting on the suitably-guided rod ofthe piston 15 which is supported on the deformable diaphragm 29, insetinside the cylinder of the device 2.

The bolts 9 of the receiver 4 previously indicated, comprise a rodrigidly fixed to a piston bolt 9 supported on the deformable diaphragm30, the piston being subjected to the action of a spring 18.

The device for simultaneously locking the panels or doors operates inthe following manner:

If action is taken on the push-rod 10 of the manual internal controldevice 1, the rod 13 drives the piston 7 supported on the diaphragm 6,displaces the volume of liquid 8 towards the receiver 4 (thedisplacement towards the device 2 not being operative due to theposition of the piston 15, at 16), the bolts 9 of which move into theirlocking position (see FIG. 4); this movement can be generated either bythe push-button 10 of the control device 1 or from either side of thevehicle by the key controls 5D-5G which operate the pinion 20 and thetoothed rod 13, following the arrangement previously described. Thelocked position is retained by the ball 11 which becomes housed insidethe cavity 12 of the toothed rod 13 by the action of the pressure spring14. The force of the ball 11 must compensate for the forces of thepressure springs 18 contained in the receivers.

Starting from this position, if the vehicle is put into movement, theautomatic control device 2 comes into operation and is modified by theaction of the regulator 3, and the piston 15 takes up the positionindicated at 16, whil the piston 7 of the device 1, which was in theposition 17, returns to 7 and the bolts 9 remain in the position shownin FIG. 4.

When the vehicle stops, the piston 15 of the device 2 returns from theposition 16 to its initial position by the action of the regulator 3 andthe total volume of the receivers 4 returns to 19, aided by the springs.18 of the bolts 9, which have a dual purpose:

(1) To activate the circulation,

(2) To permit uniform deformation of all the diaphragms 6-29-30.

In this condition, the bolts 9 have returned to their originalnon-locked state as shown in FIG. 1.

It will be notated that, irrespective of the position of the toothed-rod13, that is to say locked or not locked, the control by the devices4D-5G can be eifected and gives the bolt devices a position inverse withrespect to the first condition, which permits unlocking from the sideopposite to that at which the locking has been effected and conversely.
